The Whole 30 diet is a 30-day elimination diet that focuses on eating whole, unprocessed foods. Whole 30 is to eliminate potentially problematic food groups such as sugar, grains, dairy, legumes, and processed foods, then gradually reintroduce them to see how they affect your body. The goal is to reset your metabolism and promote healthy eating habits.

One of the unique aspects of Whole 30 is that it's not just about the foods you can eat but also the foods you can't eat. During the 30 days, you're not allowed to have added sugars, alcohol, grains, legumes, dairy, and processed foods. Instead, the emphasis is on eating a variety of protein sources, healthy fats, and fresh produce.
